I do declare the following to bea. full, clear,l

and exact description of the invention, such as will enableothers'skilled in the art to which it appertains to make and use the.

same, 'reference being had to the accon1` panying drawings, and tothecharacters of reference marked thereon, which form part of thisspecification.

The object of this invention is to provide a radiator core for internalcombustion engines which has large- Water capacity and a l`on path ofcirculation, which is comparative y easy to build, and `whichfis moresturdy and durable than any type of radia tor heretofore presented.

Briefly, the invention comprises a Vradiator whichis built up of aplurality of transversely arranged superimposed sections o1' tanks. Eachtank has an inlet at the topadjacent one end and an outlet at the botbomadjacent the other end, whereby thecirculation of the water through' thecore is through a long,l tortuous or zigzag path. Each section has frontand rear walls, and the air tubes are passed through the section and theends of the tubes fixedin said front and rear walls. Around theperiphery of each section al plurality of contiguousv air cells isprovided to assist the cooling.

In the drawin s: l

Fig. 1 is a yfro t elevation.

Fig. 2 isa vertical cross-section on line 2--2 of Fig. 1.

`Fig Iis a vertical transverse section through two sections or tanks,the crosshatching being omitted to avoid confusion.

Fig. 4 is an enlarged cross-section through the sections of Fig. 3.

`A complete radiator is shown in Fig. 1 which comprises a plurality ofsections or tanks 10, which make up the core, an upper.

receiving tank 12, and a lower tank 14. Each of the sections or tanks 10has there around a Vplurality of contiguous air-cells 15 made of thinmetal, much after the fashion of cells of well-known types of radiators.These cells extend from front torear of the core and assist the cooling.Each tank or section tilt 10has upper and lower-walls 16 and front andrear walls 18. The air cells `15 are con- -i nec'ted with these tankwalls in any suitable manner, such as by means of solder. The number ofair cells secured to the sections is preferably as indicated in thedrawings, that is, two rows of cells at the sides of the core and tworows of cells between adjacent 'sections. VA. plurality of air tubes 20are passed through each tank and the ends of said tubes are secured inthe front and rear walls or plates 1'8 as by soldering. It will be seenfrom this that the water within each tank lies around the tubes 2O andis cooled by reason of the passage of' air through said tubes 20.Cooling is further assisted by meansl of the air cells 15, which carryaway the heat radiated by the walls 16 and the ,end walls of/thesections Awhich extend vertically of the core. The inlet and outletpas.-

sages for the various sections are indicated at 22, these openings beinglined with sleeves 24 which arey soldered or otherwise secured inposition. -It will be noted that the inlet opening for each section isat one end of the upper portion of the section, and that the outletopening is at the opposite end of the lower portion. `With thisconstruction the .travel of the water isfalong a. zigzag path.

from the upper receiving tank'12 through the sections 10 to the lowertank 14.

" In building a radiator core, as many Lsections ma be constructed one uon another, as desired,`in order to get the required capacity. It willbe noted that the volume of Water which'may be contained within the coreis much larger than in present types of radiators,.wherein the Watercirculates through small cells or small tubes'. By reason of the factthat the water'is positively conducted through a long path ex tremelyeiicient cooling results, and radiation of heat from the walls of'eachsection is assisted by the passage of water through the -air cells 15 sothat the heat is readily absorbed. Another advantage of the device isits comparative indestructibility, since it is much less affected byshocks and blows than any type of radiator heretofore known. Furtherthan this, the radiator is not affected by freezing to as great anextent as in other types because of the fact that the` tubes 2O will becompressed and yield instead of being `expanded so that theywould-split. Even in the event one of the tubes should split orotherwise cause a leak, it can be temporarily sealed by plugging theends thereof with any available object, such as a piece ofwood or cloth.

Demonstration shows that the amount of water required to replenish thesupply within the core is very small. Because of the eili* cient coolingLit has been found so far to be impossible to cause .the radiator toboil.

1. A radiator core comprising a plurality of superimposed sections, eachsection hav- Ving an inlet opening in its upper wall adjacent one endAand an outlet opening in its lower wall adjacent the other end, andmeans in each section lfor cooling the contents thereof comprising aplurality of air tubes having their ends fixed in the front and rearwalls of each section and extending through the section, and a pluralityof cooling'4 cells arranged along the periphery of each sec-- tion. v.

2. A radiator core comprising a plurality of superimposed sections, eachsection having an inlet opening in its upper wall adjacent one end andan outlet opening in its lower Wall adjacent the other end, and means ineach section for cooling the contents thereof lcomprising a plurality ofcooling cells arranged around the periphery thereoi'.

3. A radiator core-section comprising a tank having upper and lowerWalls, side Walls, and front and rear walls, the upper wall having aninlet openingadjacent one end and the lower-wall having an outletopening adjacent the other end, and air tubes extending throughithe tankand having their ends fixed in the front and rear walls, there being aplurality of cooling cells arranged around the periphery of the section.

4. A radiator core-section comprising a tank, the upper portion havingan inlet opening adjacent one end and the lower portion havinfJr anoutlet o eninw ad'acent the other e P a end and a plurality of air cellscontiguously arranged around the periphery of the section.

In testimony whereof I aliix my signature.
